Title: Understanding Sensitivity of Climate with Perturbed Parameter Ensembles 

Speaker: Trude Eidhammer, NCAR

We invite you to the June RoCS Solar/Stellar Lunch. You are invited to discuss your work with colleagues.

The Section 4 seminar for the Spring of 2023 will be held on Wednesdays at 10:15–12:00 (see the schedule)

C*-algebra seminar talk by John Quigg (Arizona State University)

Dorthea Gjestvang will defend her thesis “Excitation energy propagation and angular momentum generation in the nuclear fission process” for the degree of Philosophiae Doctor at the University of Oslo, Faculty of Mathematics and Natural Sciences.

I will discuss some of our recent results on active chiral and nematic membranes. The chiral stresses we consider give rise to a novel form of odd elasticity. To outline this phenomenology I will give explicit calculations outlining spontaneous flow transitions and shape instabilities. I will discuss the relevance of these results in developmental biology and their relation to active nematics, in particular how certain limits of active nematic membranes can reduce to a theory of an isotropic membrane with an active stress defined by the deviatoric part of the shape operator.

SPARK Norway Educational Forum are monthly open meetings organized by UiO:Life Science and SPARK Norway partners.

"Physics-Informed Neural Networks for Radiative Transfer in the Solar Atmosphere"

Many have tried to adapt Clemens and Griffiths's approach to irrationality of cubic threefolds to higher dimensions, using different invariants in place of H^3(X,Z): the transcendental part of H^4, derived categories, quantum cohomology... I will report on my attempt to use higher algebraic K-theory, which turns out to be strictly weaker than what Voisin and Colliot-Thélène have already gotten from Bloch-Ogus theory, but (I think) in an interesting way. For a positive result, I can show that the higher K-theory of Kuznetsov's K3 category for a cubic or Gushel-Mukai 4-fold looks the same as that of an honest K3 surface.

Title: Environmental changes from glacier ice cores

Speaker: Margit Schwikowski, Paul Scherrer Institut
